ORA-01502: Index or partition of such index is in unusable state.

I get below Error inserting data in the table with 1 primary key and 3 foreign keys:

ORA-01502: Index '<schema.table_names_primary_key>' or partition of such index is in unusable state.

Open in new window

1st row below is the Primary key index & I do not know the Partition.

Why is this happening & How to fix this issue?

You may query
for information about the partitioned indexes (and its names)...

Then, you could try:
alter index index_name rebuild partition partition_name;

What query to write to get the partition name of this index?
Why it happened? How

select *
  from user_part_indexes a
 where a.table_name = '<here goes the table name>';

This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.
